The mean of the data is the average value of the given data. The mean of the data is the ratio of sum of all the values of data to the total number of values of data.

Walt collected random samples of data on the number of people who eat at who restaurants daily. He created two dot plots to represent his data.  

  • Restaurants A- 10,15,16,18,18,18,19,19,20,20
  • Restaurants B- 10,13,15,15,15,16,17,18,19,20

Mean of Restaurants A is,

[tex]X_A=\dfrac{10+15+16+18+18+18+19+19+20+20}{10}\\X_A=\dfrac{173}{10}\\X_A=17.3[/tex]

Mean of Restaurants B is,

[tex]X_A=\dfrac{ 10+13+15+15+15+16+17+18+19+20}{10}\\X_A=\dfrac{158}{10}\\X_A=15.8[/tex]

Degree of overlap is the difference of both the means.

[tex]DO=X_A-X_B\\DO=1.5[/tex]

Thus, the mean of the data sets of Restaurants A and B which Walt collected is 17.3 and 15.8 respectively. Degree of overlap of two data set is 1.5.
